A fifth person has died in the Upper East Side Legionnaires’ disease outbreak, as confirmatory testing found live Legionella bacteria in 34 cooling towers at 33 buildings, city health officials said Tuesday.
The Health Department said the cluster had grown to 82 cases as of July 21, with eight people still hospitalized and 56 discharged.
The agency said no new cases had been diagnosed in six days and no one had reported developing new symptoms in more than 10 days, findings it said indicate that its remediation efforts had likely eliminated the source of exposure.
The figures were released hours after City Council Speaker Julie Menin accused the Health Department of moving too slowly to contain the cluster.
She announced a September oversight hearing and plans for new legislation to strengthen public notifications and education.
The community cluster remains concentrated in Carnegie Hill and Yorkville, in ZIP codes 10028, 10075 and 10128.
Speaking earlier Tuesday at a news conference at Lenox Hill Hospital, before the fifth death was announced, Menin said residents had struggled to obtain basic information about the outbreak, including whether their buildings were affected and what precautions elderly or immunocompromised people should take.
“We learned during COVID that clear public health messaging can make or break a crisis,” Menin said, arguing that the city needed to communicate with residents earlier.
Menin said the Council would hold an oversight hearing in September to examine the Health Department’s handling of the outbreak, including the speed of testing and remediation, its communication with residents and its enforcement of cooling-tower regulations.
She said the Council plans to consider legislation to strengthen public education and resident notifications during Legionnaires’ disease outbreaks, and to require the Health Department to establish a dedicated hotline during peak summer months.
She also called for more frequent public health updates during outbreaks.
Health Committee Chair Lynn Schulman said lawmakers would also examine requiring building owners to notify tenants about whether they have cooling towers and when those systems have been cleaned.
She said the Council would consider whether existing penalties for violations are high enough.
Menin says city should have acted sooner
Menin’s sharpest criticism focused on the city’s failure, in her view, to preemptively disinfect two categories of cooling towers while initial screening was underway: those whose operators had not submitted required testing information and those near what the Health Department had identified to her as the outbreak’s epicenter.
She said the department told her shortly after the cluster was announced that it knew where the epicenter was but did not disclose that information publicly.
Menin argued that the city should have immediately begun disinfecting nearby towers and those whose operators had not complied with the new reporting requirements.
“With every hour the towers were not disinfected, with every day that they were not prophylactically disinfected, more New Yorkers became sick, and four tragically died,” Menin said.
“That is simply unacceptable.”
Menin later said she believed more aggressive preventive disinfection “would have prevented what we saw in terms of the number of deaths and the number of people who contracted it.”
In a statement to amNewYork, the Health Department rejected Menin’s criticism, saying it began investigating before the cluster reached the threshold that had previously triggered a city response.
“The NYC Health Department has responded rapidly and aggressively to this Legionnaires’ cluster on the Upper East,” a department spokesperson said.
“In the past, city protocol has been to begin an investigation after three cases have been confirmed in a tight area and time frame.
The NYC Health Department did not wait for that.”
The department said it launched its investigation after two confirmed cases and directed every building whose cooling tower returned an initial positive test result to immediately clean and disinfect the system.
“These actions have saved lives,” the spokesperson said, adding that the agency had held regular town halls and briefings for elected officials and the press while providing daily public updates.
The department said it believes its testing and remediation efforts have likely eliminated the source of exposure but is continuing to investigate where the bacteria originated and whether any building owners violated local law.
On Tuesday evening, the Health Department said confirmatory culture testing had detected live Legionella pneumophila bacteria in 34 cooling towers at 33 buildings.
All 34 towers had already been cleaned and disinfected, according to the agency.
Nine cooling towers returned negative culture results, while results for the remaining 140 systems are expected over the next week.
The department said the addresses of towers with positive confirmatory results would be updated daily on its website.
A positive culture test establishes that live bacteria capable of causing Legionnaires’ disease were present in a cooling tower before remediation.
It does not, however, establish that the tower was responsible for the outbreak, and officials have not identified the source of exposure.
The department uses preliminary PCR screening, which detects Legionella DNA but cannot distinguish between living and dead bacteria, followed by culture testing that can take approximately two weeks.
Most of the 34 culture-positive towers had also returned positive PCR results.
Four towers that were not PCR-positive later returned positive culture results and were ordered to remediate, the department said.
Two towers were PCR-positive but culture-negative, meaning the follow-up testing did not find live bacteria capable of causing illness.
In total, the Health Department said 82 cooling towers at 80 buildings had been ordered cleaned and disinfected during the investigation, and all had completed remediation.
The department said it had inspected every cooling tower that produced a positive result through either testing method, as well as an unregistered tower discovered during the investigation.
Inspectors reviewed maintenance records, operating protocols and compliance with monthly Legionella sampling requirements.
The results of those inspections are being finalized, and the department said it would issue summonses and fines where violations are identified.
Earlier, Menin said her criticism focused on the earlier period while the department was still testing the 183 cooling-tower systems in the affected area.
She argued that the city should not have waited for preliminary results before disinfecting towers near the suspected epicenter or those whose operators had not submitted required testing information.
Officials have not publicly identified the specific cooling tower or towers responsible for the outbreak.
When reporters pressed Menin on whether any delay had been directly linked to the four deaths known at the time, she acknowledged that the Council did not yet have information identifying the source.
“This is why we have so many questions that still remain unanswered,” Menin said.
Schulman said legislation she sponsored after the East Harlem outbreak last year led to new regulations requiring Legionella sampling while a cooling tower is operating, with no more than 31 days between samples, rather than the previous 90-day interval.
The regulations took effect May 8.
Menin said more than a quarter of cooling-tower operators had not submitted information required under the new reporting rules.
The Health Department said July 18 that 77% of operators citywide had submitted the required testing information, while noting that some towers that had not reported might not be operating or might not yet have begun seasonal operations.
The department said compliance is verified during inspections and that operators found to be violating the rules could face enforcement action and fines.
Menin said information showing whether fines had been assessed under the new requirement had not been posted online.
“We have to make sure that the fines are being assessed,” Schulman said, adding that lawmakers would examine whether the penalties are sufficient.
Menin also raised concerns about Health Department staffing, saying 23 water-ecologist positions were vacant.
The department said in May that it was onboarding 23 new water ecologists, which would increase its cooling-tower inspection staff to 56.
'Public health depends on public trust'
Council Member Virginia Maloney, whose district includes Lenox Hill Hospital and much of the affected area, said residents repeatedly contacted her office asking whether their buildings, drinking water and families were safe.
“Public health depends on public trust, and trust depends on timely and transparent communication,” Maloney said.
Maloney said she and her Council colleagues would pursue a real-time public-health response database, proactive cooling-tower disinfection and stronger inspection capacity.
Community Board 8 Chair Valerie Mason said residents spent the early days of the outbreak uncertain about whether their buildings had cooling towers and whether it was safe to walk outside or drink tap water.
“Information is power, and we didn’t have any of that,” Mason said.
The Health Department has stressed that the community outbreak is not connected to building plumbing systems.
Residents in the affected ZIP codes can continue drinking tap water, bathing, showering, cooking and using household air conditioners.
Legionnaires’ disease is a form of pneumonia caused by breathing in mist containing Legionella bacteria.
It is not contagious and cannot be spread from person to person.
People who live or work in the affected area, or who have visited it since late June, should contact a health care provider if they experience symptoms including cough, fever or difficulty breathing.
Those at increased risk include people who are 50 or older, smoke or vape, have certain chronic health conditions or have weakened immune systems.
This story was updated at 8 p.m. after the Health Department released the figures for July 21.
